A Hierarchical Framework for Correcting Under-Reporting in Count Data [PDF]

open access: yesJournal of the American Statistical Association, 2018
Tuberculosis poses a global health risk and Brazil is among the top 20 countries by absolute mortality. However, this epidemiological burden is masked by under-reporting, which impairs planning for effective intervention.

Modeling zero-inflated count data with glmmTMB

open access: yesbioRxiv, 2017
Ecological phenomena are often measured in the form of count data. These data can be analyzed using generalized linear mixed models (GLMMs) when observations are correlated in ways that require random effects. However, count data are often zero-inflated,

On Goodness-of-Fit Tests for the Neyman Type A Distribution

open access: yesRevstat Statistical Journal, 2023
The two-parameter Neyman type A distribution is quite useful for modeling count data, since it corresponds to a simple, flexible and overdispersed discrete distribution, which is also zero[1]inflated.

Generational Differences in Household Car Ownership

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2021
The stagnation of car demand had been observed in many countries. A similar phenomenon had emerged in Taiwan. From the perspective of socio-demographic characteristics, this study employs quantile regression for count data to investigate generational ...

Regression Models for Count Data in R

open access: yes, 2008
The classical Poisson, geometric and negative binomial regression models for count data belong to the family of generalized linear models and are available at the core of the statistics toolbox in the R system for statistical computing.

Ordinal regression models for zero-inflated and/or over-dispersed count data

open access: yesScientific Reports, 2019
Count data commonly arise in natural sciences but adequately modeling these data is challenging due to zero-inflation and over-dispersion. While multiple parametric modeling approaches have been proposed, unfortunately there is no consensus regarding how

Potential Early Risk Biomarkers for Reduced Forced Expiratory Volume in Children Post‐Hematopoietic Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

Genomic Bayesian Prediction Model for Count Data with Genotype × Environment Interaction

open access: yesG3: Genes, Genomes, Genetics, 2016
Genomic tools allow the study of the whole genome, and facilitate the study of genotype-environment combinations and their relationship with phenotype. However, most genomic prediction models developed so far are appropriate for Gaussian phenotypes.

SPARSim single cell: a count data simulator for scRNA-seq data

open access: yesBioinform., 2019
MOTIVATION Single cell RNA-seq (scRNA-seq) count data shows many differences compared to bulk RNA-seq count data, making the application of many RNA-seq preprocessing/analysis methods not straightforward or even inappropriate.For this reason, the ...

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).
